Core i5-10400F + RX 7600: bottleneck check
CPU-limited at 1440p. Mild CPU bottleneck.
The Core i5-10400F cannot feed the RX 7600 fast enough at 1440p, so the card sits partly idle in CPU-heavy games.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | CPU | 19% | mild CPU bottleneck |
| 1440p | CPU | 11% | mild CPU bottleneck |
| 4K | GPU | 13% | balanced |
This is the classic pattern: at 1080p the Core i5-10400F is the limit (19%), while at 4K the RX 7600 takes over (13% GPU-limited). If you play at 1080p on a high-refresh monitor, a faster CPU is the upgrade that matters; at 1440p or 4K this pair is already well matched.

Power supply
CPU 65 W + GPU 165 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 330 W. We recommend a 450 W unit (80 Plus Gold or better) so transient spikes from the graphics card stay inside the PSU's comfort zone. Try other pairs in the PSU calculator.
